Abstract

This paper describes the complete genome sequence of IT-227/82, a strain of avian paramyxovirus type-1 of pigeon (PPMV-1). IT-227/82 is an antigenic variant of Newcastle disease virus (NDV) of chickens. The genome is 15,192 nucleotides (nt) long, similarly to the previously published NDV strain ZJ1. It is, however, six nt longer than the genomes of NDV strains LaSota/46 and Beaudette C. The six-nt insertion was located in the 5' non-coding region of the nucleoprotein (NP) gene. The presence of this six-nt insertion showed no correlation with the virulence or the reservoir of the NDV strains sequenced so far. The genome length of 15,186 or 15,192 nt can be connected however, to "old" (I, II, III and IV) and "new" (V, VI, VII and VIII) NDV genotypes, respectively. Comparison of open reading frames indicated that the PPMV-1 strain IT-227/82 encodes the longest W protein, (227 amino acids). The length of the W protein showed remarkable differences even within genotypes and cannot be regarded, therefore, as a phylogenetic feature. The haemagglutinin-neuraminidase protein of strain IT-227/82 consists of 571 amino acids, similarly to genotypes IV, V and VII NDV strains, while genotype I and II strains have longer HN proteins, 616 and ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
